U.S., India To Collaborate On Mars, Earth Missions


One of the working group's objectives will be to explore potential coordinated observations and science analysis between MAVEN and MOM, as well as other current and future Mars missions.

"NASA and Indian scientists have a long history of collaboration in space science," said John Grunsfeld, NASA associate administrator for science.

"These new agreements between NASA and ISRO in Earth science and Mars exploration will significantly strengthen our ties and the science that we will be able to produce as a result."

The joint NISAR Earth-observing mission will make global measurements of the causes and consequences of land surface changes. Potential areas of research include ecosystem disturbances, ice sheet collapse and natural hazards.

NISAR will improve understanding of key impacts of climate change and advance knowledge of natural hazards, NASA said.

NISAR will be the first satellite mission to use two different radar frequencies (L-band and S-band) to measure subtle changes of Earth's surface associated with motions of the crust and ice surfaces less than a centimetre across.

This allows the mission to observe a wide range of changes, from the flow rates of glaciers and ice sheets to the dynamics of earthquakes and volcanoes.

Under the terms of the new agreement, NASA will provide the mission's L-band synthetic aperture radar (SAR), a high-rate communication subsystem for science data, GPS receivers, a solid state recorder, and a payload data subsystem.

ISRO will provide the spacecraft bus, an S-band SAR, and the launch vehicle and associated launch services.

The agency developed a partnership with ISRO that led to this joint mission. The partnership with India has been key to enabling many of the mission's science objectives, NASA said.

NASA and ISRO have been cooperating under the terms of a framework agreement signed in 2008.
